concrete Flashcards
what are the basic properties of concrete?
fine or course grain, portland or pozzoland, and water
it is a regular concrete with a basic mix of cement, aggregates and water
normal strength concrete
what is the ratio in making a normal strength concrete
1:2:4
what are the commonly uses of normal strength concrete?
pavement, home construction, and buildings that don’t require max. tensile strength
it is the simplest form of concrete
plain concrete
this type of concrete has no reinforcement and has the same mix ratio with normal strength concrete
plain concrete
what are the common application of plain concrete?
pavements and walkways
it has lower density and high water content, and has lightweight aggregates
lightweight concrete
what are the common application of lightweight concrete?
walls, flooring and plastering
it is made at a manufacturing plant and mixed during travel
ready mix concrete
what are the common applications of ready mix concrete?
building and roads
it is made of lime and shale-based portland cement
polymer concrete
what are the common uses of polymer concrete?
swimming pools, sewer structure
recycled glass is added on aggregate
glass concrete
what are the common uses of glass concrete?
countertops, floors, tiles
it is made with reinforced bar to improve the tensile strength
reinforcement concrete
what are the common uses of reinforced concrete?
beams, columns, suspended slabs, bridges
it is more porous which causes water to pass through to groundwater
pervious concrete
what are the common uses of pervious concrete?
walkways, ramps, pavers
it has compressive stresses applied to it during production
prestressed concrete
what are the common uses of prestressed concrete
bridges, beams, suspended slabs, roofs
what are the two types of prestressed concrete?
pre tension and post tension
it is molded and curve, and ready to use
pre-cast concrete
what are the common uses of pre-cast concrete?
mass housing, high rise building
